So I just started playing on the TBC server and all was fine. I was even able to install some addons. I had no problems the first couple of days but now I go from big d*ck fps to barely any in the span of seconds. Ive tried doing the thing with enabling all my cores but it doesnt seem to work. Any other suggestions?
Your problem sounds similar to what I experienced few days ago. Do you use Avast antivirus? They've had an update that ****s some of us over. If you do, it worked for me after i uninstalled it. Hope this works for you too!
